They’re all reborn, what’s wrong with being a little more almighty?

Chapter 29 Success! (Seeking for further reading)

The first snow in 2002 may come later than usual. But the first snow in 2003 was not late.

The gate building of Tsinghua Garden was originally white, blending with the surrounding snow, like a quiet picture under the swirling snow. Under the plaque of "Shui Mu Tsing Hua", the red walls and black tiles are dotted with traces of white snow, full of ink-like elegance.

In class, the professor began to give a long lecture again, talking about some extra-curricular content that was not in the textbook.

Zhang Wei tried hard to listen for more than ten minutes, but he still couldn't keep up with the rhythm.

"Forget it, stop learning, destroy it!" Zhang Wei sat down on the stool.

At this time, Zhang Wei had completely given up on the plan of "study hard and make progress every day". As long as he didn't fail the class at the end of the semester, he would have achieved his learning goals.

Study discussion group? Don’t go, don’t go!
After-school student club? No me, no me!
Department group activities? Please ask for leave!
I still have to focus on the project of extracting graphene. If I get the graphene out one day early and publish the paper, everything will be fine!
……

Department of Physics, Tsinghua University, in the laboratory, Chen Mingzheng is wearing a white coat, mask and goggles, operating a very sophisticated experimental machine.

Behind Chen Ming, Professor Fang, who had gray hair on his temples, was looking at his proud disciple with pride and said at the same time;
"Chen Ming's hands were born to do experiments! Look at how stable the operation is. Even doctoral students who have practiced for three to five years are not as good as him."

Next to him, another old man nodded with deep approval: "Seeing is better than hearing. I heard that you have found a genius. I didn't believe it at first, but now I'm convinced! It's him, please. I’ll give it two weeks!”

"No, I still have a lot of experiments to do here. Without explanation, the progress will be delayed!" Professor Fang said.

"Didn't you promise me before that you would lend it to me? Why did you regret it?"

"This is not a regret. I said before that I wanted to lend someone to you, but at that time, you didn't think that the person was autistic, so you didn't want it!"

"I mean, I don't want it for the time being. The latest polishing machine hasn't arrived yet! It's useless for me to ask for help!"

The other party paused for a moment, then continued with a rogue expression: "Anyway, all my people are here, you can't let me go back empty-handed! Otherwise, I will live here today!"

"Okay, Lao Wu, you can take him away, but let's talk ugly up front, and your School of Materials Science can't bully him!" Professor Fang said.

Professor Wu suddenly beamed with joy: "Lao Fang, don't worry! I count on him to help me cut graphite sheets, how can I bully him! I will invite him back to the School of Materials and I will treat him as an ancestor!"

Professor Wu brought the autistic man back to the School of Materials Science and Technology.

"Chen Ming, you will come to my place temporarily in the next two weeks. The conditions here are much better than those in your physics department. There are not only laboratories here, but also lounges!
Right over there, there is a TV, various newspapers and magazines, and a ping-pong table. Next to the lounge is the tea room, where you can eat all kinds of snacks for free. What do you want to eat? I'll get it for you? "Professor Wu said with an attentive look.

"Instant noodles, white elephants with big bones." The autistic man said.

"Uh, it seems like there really isn't one."

Professor Wu smiled awkwardly. The cafeteria of Tsinghua University is so rich, even dogs won’t eat instant noodles!

"How about something to drink first? We have more than a dozen kinds of drinks here! Coke, Sprite, Fanta, 7up, Pulse, Red Bull, yogurt, coffee, what would you like to drink?" Professor Wu then asked.

"I want to drink beer." The autistic person raised another problem.

"Uh, there's no such thing..."

What kind of laboratory would keep something like beer? Professor Wu complained in his heart.

"So poor!" Two words came out of the autistic man's mouth.

Professor Wu was choked and suddenly had a black line on his face. "Forget it, I'll take you to visit the laboratory first!" Professor Wu led the autistic man into the laboratory of the School of Materials.

"This one is the polishing machine just introduced by our School of Materials. This machine is currently the most advanced in the world, and its processing accuracy reaches the micron level!"

As Professor Wu spoke, he took out another thin piece of graphite and continued, "Your task is to polish this thing and make it as thin as possible. The thinner the better!"

The autistic man did not answer, but nodded directly.

The autistic person's indifferent reaction made Professor Wu feel like he was perfunctory.

"This won't work. You have to give him a beating. If he's so casual, he won't be serious when doing experiments!"

So Professor Wu said: "Chen Ming, you must pay attention to this experiment. Not to mention the introduction of the world's most advanced polishing machine, we spent a lot of money. Just this thing in my hand, Do you know how precious this experimental material is? Do you know how valuable this thing is?"

"Highly directional pyrolytic graphite! Retail price is one yuan per piece, and wholesale discounts are available." The autistic man repeated Zhang Wei's original words like a machine.

Professor Wu was suddenly speechless and could not continue what he said.

Wait, it’s only one yuan a piece, and there’s a wholesale discount? Why is the one I bought so many times more expensive than this? My XXX! The buyer got a kickback!
……

Zhang Wei is not the only one who wants to extract graphene. Scientists all over the world want to extract graphene, including the School of Materials Science and Technology of Tsinghua University.

In the past few years, scientists tried to use chemical methods, but no one succeeded, so many scientists returned to traditional methods.

The first is the cutting method. This method is impossible even if you think about it. Graphene is essentially a layer of atoms. How can you cut a layer of atoms out? Going to open Lanzhou Ramen will definitely make more money than doing experiments!
In addition to cutting, another method is grinding. Since I can't cut out a layer of atoms, I will grind it little by little. In theory, I can grind it to a thickness of one layer of atoms.

This was also the method most used by scientists at that time, and the premise of this method was that it required a high-precision polishing machine and a top-notch operator.

The minimum standard for this operator is the micro-operation of a level nine fitter.

According to data, in 2004, some laboratories had polished the thickness of graphite to 1 micron, but a 1-micron graphite sheet still had more than a thousand layers of graphene, which was still far from success.

……

In the rental house, Zhang Wei placed a sample under the electron microscope and then looked at the display screen.

"Light brown! This piece shows light brown!"

Zhang Wei felt his heartbeat begin to accelerate. He shook his right hand vigorously with his left hand to stop his hands from shaking, and then carefully put the sample into the spectrometer.

Spectral lines slowly appeared on the computer screen, and the spectral structure of this sample was also displayed in front of Zhang Wei.

One of the perfect single-Lorentz peak shapes fell into Zhang Wei's eyes.

Zhang Wei rubbed his eyes and saw that he was right. It was indeed a single Lorentz peak spectral curve.

"I succeeded! This is graphene!"

　Thank you Chow Yun-fat for your support! The number of words is still relatively small, and if you feel that it is not satisfying, you can read "The All-Around Athlete" written by Guan before. It is a fast-paced pretense, with no connotation, and it is just a fun read. I have put the link of the book in the book recommendation below. Click it to read it directly. If not, just upgrade to the latest version of Qidian APP to see it.
